Americans with Disabilities Act of 1990

Title II of this act (42 U.S.C. 12131 et seq.) prohibits discrimination against persons with disabilities:

(a) any State or local government;
(b) any department, agency, special purpose district, or other instrumentality of a State or States or local government; and
(c) the National Railroad Passenger Corporation, and any commuter authority (as defined in section 103(8) of the Rail Passenger Service Act).

Further, section 202 also alludes to captioning:

Subject to the provisions of this title, no qualified individual with a disability shall, by reason of such disability, be excluded from participation in or be denied the benefits of the services, programs, or activities of a public entity, or be subjected to discrimination by any such entity.

Section 402 states:

Any television public service announcement that is produced or funded in whole or in part by any agency or instrumentality of Federal Government shall include closed captioning of the verbal content of such announcement. A television broadcast station licensee:

1. shall not be required to supply closed captioning for any such announcement that fails to include it: and
2. shall not be liable for broadcasting any such announcement without transmitting a closed caption unless the licensee intentionally fails to transmit the closed caption that was included with the announcement.”
